Aren't most of the stories written around these three rules about ambiguities and loopholes ... The Laws were a starting point, and his fiction was a decades-long exploration of why starting points are never enough.
Yes, and the point you quoted still stands, they are a starting point.
The always relevant XKCD comic explains it well enough: those laws in that order are essential as the starting point. Different order or missing entirely is guaranteed bad. But as pointed out through all kinds of science fiction writing, there are many ways we can understand they are insufficient.
Right now I'd agree they're exactly backwards, or as the XKCD comic described, on track to become a "killbot hellscape". We need even more rules and regulations than that, but as a set of fairly obvious first steps penned 80 years ago, they're pretty blatantly an essential first draft of baseline rules that are missing today.
